INON UFL-GR140 Pro ZD Underwater Semi-fisheye Conversion Lens
- Multi-coating optical glass
- Ultra wide angle of view 140° underwater
- DoF underwater will be extended to 4cm/1.6in to infinity
- Professional-level image quality
- Speedy lens exchange by INON ZD mount
The UFL-GR140 Pro ZD provides wild wide underwater footage nearly same view angle as using action camera on land.
Supports Large Image Sensor, Large Aperture Semi-fisheye Lens
The rear lens group has been enlarged while maintaining the same size and weight as the previous model.
Works well with action cameras with large sensors, such as the Insta360®Ace Pro, to film at the maximum field of view without vignetting.
Shooting at 8:7 aspect ratio of GoPro®HERO11 and later models are also supported without vignetting.
Ultra Wide Even Underwater
Though an action camera is equipped with ultra wide lens, its coverage underwater will dramatically narrow down due to different refraction ratio between air and water.
For example, maximum angle of view of GoPro® HERO13 Black is approx. 156° on land which will narrow down to approx. 94° when we put the camera in genuine dive housing and bring it underwater due to different refraction index. The INON UFL-GR140/UFL-GR140 Pro provides ultra wide semi-fisheye imaging with angle of view 140° underwater enabling wild underwater video work only with action cameras.
Dynamic CFWA Imaging
Shooting through the INON UFL-GR140/UFL-GR140 Pro lens enables you to shoot a subject at close range to benefit deformed and/or perspective result.
The native depth of field (DoF) of the GoPro®HERO13 Black on land is approx. 60cm/2ft to ∞. With the INON UFL-GR140/UFL-GR140 Pro, DoF underwater will be extended ∞ 4cm/1.6in to ∞ closer to camera side.
Professional-level Image Quality
Both UFL-GR140/UFL-GR140 Pro lenses are optimized to produce quality images from the minimum focusing distance to infinity. A 5-layer multi-coating on the inner surface of the acrylic dome ensures excellent image quality comparable to that of a glass dome, while keeping budget price.
